I'm imaging an upcoming wedding that seems to be going well, until the mother of the bride starts sending out messages such as: "Everyone is expected to meet at least a 'silver' contribution level of approved items on the gift registry. This is easy for anyone who deserves an invitation for this special occasion."

It would be pretty foolish to just... ignore the subtext.

I suppose in this case, an angered "momzilla" can get you fired, freeze your bank account, etc.
